thereof and'engine suction and the atmosphere, respectively, and a valve mechanism for controlling discharge of fuel from said vessel operated to open position solely by breaking of a vacuum in said vessel.

in a vacuum fuel feeding device for engines, a reciprocal fuel feeding vessel having predetermined raised and lowered positions, means constantly tending to move said vessel to raised position and adapted when the vessel is held raised thereby to be overcome by weight of accumulated fuel within the vessel whereby the latter is moved to lowered position, a constantly open fuel supply connection between a source of sup ply and the interior of the vessel, and means operated by raising and lowering movements of said vessel to effect and out OK communi cation between the interior thereof and engine suction and the atmosphere, respec tively.

In a vacuum fuel feeding device for engines, a reciprocal fuel receiving vessel normally disposed at one limit of its movement and operated to its other limit of movement by weight of accumulated fuel therein, said vessel having constant communication with a source of fuel supply, a valve controlled communication with the engine suction open when said vessel is in its normal position and closed when said vessel is moved to its other position by weight of accumulated fuel therein, and means operated by movement of the vessel under the influence of the weight of accumulated fuel therein to place the interior thereof in communication with the atmosphere.

In a vacuum fuel feeding device for engines, a. reciprocal fuel receiving vessel normally disposed at one limit of its movement and operated to its other limit of movement by weight of accumulated fuel therein, said vessel having communication with a source of fuel supply, a valve controlled communication with the engine suction open when said vessel is in its normal position and closed when said vessel is moved to its other position by weight of accumulated fuel therein, and means operated by movement of the vessel under the influence of the weight of accumulated fuel therein to place the interior thereof in communication with the atmosphere at a point above the fuel level therein.

5. In a vacuum fuel feeding device, an outer tank, a reciprocable inner tank movable to raised and lowered positions, weight means for raising said inner tank which latter is adapted to be moved to lowered posi-' tion by weight of accumulated fuel therein, air inlet and oulet means to and from said inner tank, and means operated by the fluid in said inner tank reaching a predetermined level to open said air inlet and to close said air outlet means.

6. In a vacuum fuel feeding device, an outer tank, a reciprocal inner tank movable to raised and lowered positions and adapted to be moved to lowered position by the Weight of accumulated fuel therein, means for raising said tank when the weight of the fuel therein reaches a predetermined low value and a valve fixed with respect to the inner tank cooperating with a seat on the outer tank to control communication between the inner tank and the atmosphere, said valve when seated permitting oscillatory movement of the inner tank.

7. In a vacuum fuel feeding device, an outer tank, a reciprocal inner tank movable to raised and lowered positions and adapted to be moved to lowered position by the weightv of accumulated fuel therein, means for raising said tank when the weight of the fuel therein reaches a predetermined low value and a valve fixed with respect to the inner tank cooperating with a seat on the outer tank to control communication between the inner tank and the atmosphere, said valve and said valve seat being of spherical contour whereby the valve when seated permits oscillatory movement of the inner tank.

8. In a vacuum fuel feeding device, an outer tank, a reciprocal inner tank movable to raised and lowered positions, weighted fulcrumed arms carried by the outer tank, a tube extending through and affixed to said inner tank, said arms cooperating with said tube to hold the inner tank normally raised, said inner tank being adapted to be moved to lowered position by the weight of accumulated fuel therein, a sealed chamber disposed about said tube, a pair of air pipes and a fluid pipe communicating with said chamber, and a valve common to an end of said tube and an end of said fluid pipe.

In witness whereof I have signed this specification in the presence of two witnesses.
